Saturated - Transfats and Cholesterol
There evidence linking the fats in your blood with arterial damage or atherosclerosis. The three main fats in your blood are low-density cholesterol (LDL) or bad cholesterol,the high-density cholesterol (HDL), and a butter-like substance named triglycerides. The higher your LDL and triglycerides, the higher your chances of developing clogged arteries.
Saturated fats are mainly animal fats such as lard and butter. They raise your Bad (LDL) cholesterol and aid in developing arterial disease. These fats enter the blood, stick to the blood vessel walls and narrow the arteries.
Trans-fatty acids are vegetable oils that went through a process called hydrogenation. That turn the oils into a solid such as shortening or margerine.
Trans-fatty acids act like saturated fats by increasing bad cholesterol (LDL) in the blood. Transfats are found in commercially baked goods such as muffins and donuts. Try to eliminate them.
Bad cholesterol (LDL) can be reduced by drugs and a diat including healthier fats.
